This is where you can find the downloads you need. Some may have several options.
1. Hitman Pro - Pros: Can launch from USB, takes up 10mb, cleans malware, viruses, trojans, worms, keyloggers, rootkits, trackers, and spyware. Cons: Costs money ($24.95, One-time pay.), but has 30-day trial.
2. Malwarebytes - Pros: Has free license, is upgradable for $8.33/mo (VPN included) for 5 devices, other plans cheaper (as low as 3.33/mo no vpn). Cons: Forces you to start with premium trial for 14 days. Will not charge you unless you have a credit card linked.
